Abstract
Provided are a polymerizable group-containing and fluorine-containing adamantane derivative capable of affording a cured product having good heat resistance, good mechanical properties such as surface hardness and a low refractive index, a resin composition containing such a polymerizable group-containing adamantane derivative, and a fluorine-containing adamantane derivative which is useful as a reaction intermediate used for the production of the polymerizable group-containing and fluorine-containing adamantane derivative. Specifically provided are a fluorine-containing adamantane derivative represented by the general formula (I) below, a polymerizable group-containing and fluorine-containing adamantane derivative represented by the general formula (II) below, and a resin composition containing such a polymerizable group-containing and fluorine-containing adamantane derivative. In the formulas, Xand Xeach represent OH or NH, a, b and c each represent an integer of 0 or more and a+b+c≧1, for example a=b=0 and c=1, Zrepresents, for example, —CH—, s and t each represent an integer of 1 to 15, u represents an integer of 0 to 14, s+t+u=16, for example s=2, t=14, u=0, and Xrepresents, for example, —O—CO—CH═CH.
